00:12:206 (1,4) - Ranking Criteria: Avoid overlapping circles, slider heads, and slider tails. These can be confusing for new players. 1/2 overlaps due to distance snapping are an exception.
00:14:006 (5) - I feel that this slider doesn't fit the structure of this section, as it requires you to make the downbeat at 00:14:606 not clickable unlike what you did earlier, for example 00:00:206 (1), 00:05:006 (1), 00:09:806 (1).
If you want to add variety, I recommend making it ends at 00:14:456 and put something active at 00:14:606 instead.
00:18:206 (4) - Likewise. I'd also not recommend changing the SV at all. And if you must, change it by 0.05x - 0.1x
what do you mean by this 00:18:206 (4) - changing it into 0.05x - 0.1x? I think its speed is fairly fine. Consider it res
00:24:206 (1,2), 00:29:006 (1,2) - The way you choose to map these sounds differently from others (From Slider -> circle to Circle -> slider) makes the structure of this section appears weaker.
While varieties are always a good thing, I'd recommend doing it when the section is different rather than it staying the same!
00:56:006 (2,3) - The inconsistent spacing here is caused by suddenly changing the SV. This is why I don't recommend changing it, as when you map with distance snapping enabled, things like this can occur.
01:02:906 - I find this build-up section a bit unintutive and plain. Long chains of circles only should be avoid when you map a lower difficulty.
I'd recommend adding some varieties to this section to support the build-up in intensity. Something like https://i.imgur.com/nXBU5p8.png
01:45:806 (1,2,1,2) - I find this section a bit hard to read. Newer players decide when to click by looking at the spacing, and they can't really tell the different between them. https://i.imgur.com/4MdZZIH.png
I'd make 01:46:556 (1) - a 1/1 slider instead.
02:10:106 (2,3,4) - "Avoid more than three actively clicked 1/2 rhythms in a row."
This kind of rhythm should be reserved for hard and above difficulties only.
However, 01:55:406 (1,2,3) - is fine and serves the same purpose, I recommend changing it to this instead.
02:52:406 (5) - double reverses shouldn't be used at low diffs since players are expecting one
